Application filed December 8, 1919. Serial No. 343,289.

To aZZ whom it may concern: v

Be it known that 1, CHARLES A. MARIEN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Automobile-Radiators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

The present invention is directed to improvements in automobile radiators, particularly of the type especially adapted for touring and passenger cars in contradistinction to trucks, though obviously I am not to be limited to the class of vehicle to which I may apply the invention. The object of the.

invention is to provide a radiator with a demountable core, that is to say, a core which may be readily detached as a unit from the outer frame (permanently secured to the machine) for purposes of repair and the stoppage of leaks, and then quickly restored to the frame for further service. A further object is to provide a radiator of the character referred to which shall be simple, one in which the component parts may be assembled'in a minimum amount of time, one which shall present a neat appearance, especially from the front of the machine, one

be cheaply constructed, and one possessing further and other advantages better apparent from the following detailed description in connection with the accompanying drawings, in which- Figure 1 represents a front elevation'of the improved radiator; Fig. 2 is a rear elevation thereof; Fig. 3 is an enlarged vertical cross-section on the siz-zag line 3-3 of Fig. 2 broken in the middle; Fig. 4 is a side elevation of the radiator; and Fig. 5 is a top plan thereof.

, Referring to the drawings, 1 represents the outer frame carried by, and secured to, the vehicle body in any approved mechanical manner, said frame being provided with a top hollow circulating compartment or tank t and a bottom hollow circulating compartment or tank If, the said tanks with the exception of the'rear walls thereof belng made, preferably of sheet metal, said rear walls being of cast metal. top and bottom tanks form a rigid frame for the reception of the core, the latter being composed of a top hollow circulating head 2, and a bottom hollow circulating head 2, the said heads being connected by the inter which may The sides, and

mediate'orbody portion C which may be of any standard type of cellular construe tion of radiator core well known in the art. The middle of the rear wall of the tank t is tapped by the water circulating feed pipe 3, the corresponding portion of the rear wall of the tank t being tapped by the discharge or-o'utlet pipe 4- as'indicated inthe drawings. 1

Cast with the rear wall of the tank t and disposed on each side of the pipe 3, and in free communication with the interior of the tank, is a goose-neck or bend 5, the

free end whereof, when the parts are assembled, registers with an opening 0 in the rear wall of the hollow head 2 of the core. The goose-neck at its discharge terminal is formed with side lobes d which are perforated to receive suitable studs or studbolts 6 projecting from the rear wall of the head 2, the cap nuts n finally securing the goose-necks to the head. packing strip or gasket 7 is interposed between the goose-neck and the wall of the head 2. Thesame arrangement prevails at the bottom of the radiator, the rear wall of the tank if having cast therewith the goosenecks 5 the intake ends of which. communicate with the head 2 of the core through the discharge openings 0 formedv in the rear Wall of said head, the goosenecks being secured to the head by the nuts 72 on the stud bolts 6 leading from the rear wall of the head,,the same as in the case of the goose-necks 5. When the parts are properly assembled the circulation of the water through the radiator is as indicated by the arrows in Figs. 3. The goosenecks or bends 5, 5, being in the rear, that is to say, on the same side with the feed and discharge pipes 3, 4, must necessarily be disposed on either side of said pipes, so that there can be no direct flow or short circuiting of the current from and to said pipes through the goose-necks. The absence of shortcircuits or local currents results in an even distribution or diffusion of the water throughout the tanks and core- 7 Preferably, a

drawn position is shown dotted in Fig. 3.

In reinserting the core into the frame, the same is pushed back until arrested by' the free ends of the bends 5, 5, which, as shown,

project inwardly toward and opposite the opening of the frame into which the core is inserted. In restoring the core to the outer frame the stud-bolts 6 enter the several vided with a flange a for the support of the adjacent end of the hood H. Features shown but not alluded to'are well known in the art and require no description in the 7 present connection.

Having described my invention what I with water-circulating compartments or tanks, a demountable core inserted into the frame from one side of said frame, Water circulating pipes carried the tanks on the opposite side and extending opposite the opening of the frame for arresting the in; ward movement of the core into the frame, and means for securing the free terminals of said pipes to the core.

In testimony whereof'I aflix in presence of two witnesses,
